2.1.4 Remote BJT

Q1 is a MMBT3904T NPN BJT, and these temperature limits are used as the remote temperature sensor on the EVM. A PNP footprint located on the back of the EVM (Q2) allows the user to evaluate both types of transistors. The MMBT3904T is on a perforated section of the board that can be broken off to connect different remote sensors.
